I don't believe that it doesn't currently work with 64-bit binaries though, so
if you want to run the profiler, you're going to need to do it with a 32-bit

Someone who has actually done a C or C++ application or two which used D code

here who have done that, but I've never done it myself.

Are you sure that the call requires the string to be null terminated? I

Does it 'leak'? What is your exact setup, why isn't the GC collecting

Don't use length, use std.utf.count, ala:

alias toUTFz!(const(wchar)*, string) toUTF16z;

I like to keep that alias for my code since I was already using it beforehand.

Yeah that was already planned, no worries. :)
In D2, how can we get the output of running a script.
We can use 'system' to run the script, but how we cannot assign the
standard output of the running script. Is there any way to do it, or
whether it will be included into future version of std.process? Thanks a
lot.

still is not synced well.
